Is there anything literally "bad" about having the 6-ports stay closed, like, harmful or anything. I know it takes away about 15hp, but other than that, is there any negatives????

 

no the car will run fine without them.

 

Yep, it'll be fine... I prefer low end torque at 3000 rpm to a couple of horses at 6500 anyway, at least when i'm just driving around town. My actuators are off right now, with the valves wired closed(until tomorrow when the entire 6 port assembly comes out). You could wire them open for that extra hp at high rpms, but to me the loss of low end makes it not worth it.

Yep.. just fine. Completely removing the actuators is probably the best option, as it gives even more high end, and gives back a little low end. Once you REALLY mod your n/a, the 6p's become a restriction, so removing them helps even more.

Tesla, this comment is made in good cheer.......lets see now, Mazda put on the aux port actuators to take away the low end and while they were at it had it take away the top end also? Or did I misread again?(probably).

 

Ya, removing the 6 ports are the ONLY way to go if you've done a lot to your 7 (lots more flow)... I had no low end torque anyways, so I figured I might as well take em right out. DAMN!!! It made a huge difference, and it feels a lot more natural.. (hard to explain, but the power curve feels more linear) I also removed the ACV and A/P at the same time... but I'm sure I can contribute the gobs of extra power at 5500-8500 to the sleeves being gone....

 

What I mean is that completely removing the ports is better than tying them open, for both low and high end. You gain a little over tying them open in both the high and low end because the airflow is smoother than with the port in. I hear the low end gain is small, but noticeable. Plus, it's more crap to get out of your engine bay!

Having them close is of course better for low end only...but if you get crazy, low end loses it's meaning anyway..

This argument comes up in every auxilary port post.
Until sometime shows me real proof, I tend to believe that Mazda didn't add all that extra junk for nothing, and the car will run best with the system working as it should.
Most of what I hear is just reguritated crap that other forum members said. Remember, just because you read it here doesn't mean its true kiddies.

 

Were not talking about stock cars here. Were talking about very modded n/a's, some making 40% more hp than stock(like me). After a few mods, the 6 port sleeves become more of a restriction everywhere, and hurt hp. Removing them frees up some hp, and makes the engine have a lot better top end. Also simplifies it quite a bit.

Yes Mazda did put them on there for a reason, to give *stock* n/a's more low end, while still having a good top end. Once the mods stack up, and the hp climbs, theyre nothing more than a restriction. Also, who really worries about low end when you want a fast rotary anyways? And I bet my car has more low end than a stock n/a, and a hell of a lot more top end. I have a lot of mods, including reomved 6 port sleeves.
